Size Extensive Auxiliary-Field Quantum Monte Carlo with Perturbative Coupled Cluster Trial Wavefunction
Yichi Zhang, Ankit Mahajan, Yann Damour +1
In this work, we develop a size extensive Auxiliary-Field Quantum Monte Carlo (AFQMC) approach that scales as for local energy evaluation by treating the Coupled Cluster S…
Systematic improvement of trial states in phaseless auxiliary-field quantum Monte Carlo
Eirik F. Kjønstad, Yann Damour, Sandeep Sharma +1
We extend the use of coupled cluster (CC) trial states in the phaseless auxiliary-field quantum Monte Carlo (AFQMC) method beyond single and double excitations to include both trip…
Excited State Absorption: Reference Oscillator Strengths, Wavefunction and TD-DFT Benchmarks
Jakub Širůček, Boris Le Guennic, Yann Damour +2
Excited-state absorption (ESA) corresponds to the transition between two electronic excited states and is a fundamental process for probing and understanding light-matter interacti…
Selected Configuration Interaction for Resonances
Yann Damour, Anthony Scemama, Fábris Kossoski +1
Electronic resonances are metastable states that can decay by electron loss. They are ubiquitous across various fields of science, such as chemistry, physics, and biology. However,…
Stochastically accelerated perturbative triples correction in coupled cluster calculations
Yann Damour, Alejandro Gallo, Anthony Scemama
We introduce a novel algorithm that leverages stochastic sampling techniques to compute the perturbative triples correction in the coupled-cluster (CC) framework. By combining elem…
Go Green: Selected Configuration Interaction as a More Sustainable Alternative for High Accuracy
Pierre-François Loos, Yann Damour, Abdallah Ammar +3
Recently, a new distributed implementation of the full configuration interaction (FCI) method has been reported [Gao et al. J. Chem Theory Comput. 2024, 20, 1185]. Thanks to a hybr…
